I find this is an issue on every forum I've been a member of.

People have to realize that by even asking a question, they already are testifying to their ignorance on that matter. I'll agree with LadyOh in that no one really enjoys being told they're wrong, but part of it is in the delivery. I've seen some newbies get totally flamed and bashed for making a very small error in their husbandry (I've been guilty of it myself in earlier years).

But I do get irritated when people ask for help, receive good advice and then choose not to use it. This is a clear definition of stupidity in my book: a conscious decision to choose not to implement wisdom and knowledge.

I also do get perturbed when people with no experience on a matter claim to be "experts". When I give advice, I try to start off with a disclaimer, somthing to the effect of, "Well, this is just what I've heard~" or "My experience has been~" or "I'm no ___ expert but this is what I know~".....just to make sure people can take what I say with a grain of salt.
